This tests contains an app with a main page and sub pages. The main page contains a list of buttons; each button leads to a designated sub page when tapped on. Each sub page should displays some simple UIs to screenshot tested.
The flutter driver test runs the app and opens each page to take a screenshot.
Use test_driver/flutter_gold_main_test.dart
to test against golden files stored on Flutter Gold. Otherwise, use main_test.dart
to test against golden files stored on test_driver/goldens/<some_test_page_name>/<device_model>.png
.
Note that new binaries can't be checked in the Flutter repo, so use Flutter Gold instead.
